Embodiment 1
[0031] The preparation of embodiment 1 burdock fruit dregs
[0032] (1) Place the dried burdock fruit in subcritical equipment after being pulverized, use butane as the medium to subcritically extract the burdock fruit, remove the burdock fruit oil, and obtain burdock fruit residue;
[0033] (2) extract the burdock fruit dregs with ethanol, and separate the extract to obtain the burdock fruit dregs.
[0034] The extraction parameters of the subcritical equipment described in step (1) are: extraction pressure 35MPa, extraction temperature 55°C, CO 2 The flow rate is 1.5ml / min, the extraction time is 60min, the analytical pressure is 10MPa, and the analytical temperature is 35°C;
[0035] The extraction in the step (2) refers to heating and reflux extraction; the specific method is:
[0036] The residue was extracted by heating under reflux with ethanol with a volume fraction of 70%, the number of extractions was 2 times, each extraction time was 1.5h, and the ratio of residue...
